WARNING

■

When refueling the vehicle

Observe the following precautions

while refueling the vehicle. Failure

to do so may result in death or

serious injury.

●

After exiting the vehicle and

before opening the fuel door,

touch an unpainted metal sur-

face to discharge any static

electricity. It is important to dis-

charge static electricity before

refueling because sparks result-

ing from static electricity can

cause fuel vapors to ignite while

refueling.

●

Always hold the grips on the

fuel tank cap and turn it slowly

to remove it.

A whooshing sound may be

heard when the fuel tank cap is

loosened. Wait until the sound

cannot be heard before fully

removing the cap. In hot

weather, pressurized fuel may

spray out the filler neck and

cause injury.

●

Do not allow anyone that has

not discharged static electricity

from their body to come close to

an open fuel tank.

●

Do not inhale vaporized fuel.

Fuel contains substances that

are harmful if inhaled.

●

Do not smoke while refueling

the vehicle.

Doing so may cause the fuel to

ignite and cause a fire.

●

Do not return to the vehicle or

touch any person or object that

is statically charged.

This may cause static electricity

to build up, resulting in a possi-

ble ignition hazard.

■

When refueling

Observe the following precautions

to prevent fuel overflowing from

the fuel tank:

●

Securely insert the fuel nozzle

into the fuel filler neck.

●

Stop filling the tank after the fuel

nozzle automatically clicks off.

146

4-4. Refueling

Pull up the opener to open
the fuel filler door.

Turn the fuel tank cap slowly
and remove it, then hang it
on the back of the fuel filler
door.

After refueling, turn the fuel tank
cap until you hear a click. Once
the cap is released, it will turn
slightly in the opposite direction.

WARNING

●

Do not top off the fuel tank.

NOTICE

■

Refueling

Do not spill fuel during refueling.

Doing so may damage the vehi-

cle, such as causing the emission

control system to operate abnor-

mally or damaging fuel system

components or the vehicle’s

painted surface.

Opening the fuel tank cap

Closing the fuel tank cap

WARNING

■

When replacing the fuel tank

cap

Do not use anything but a genu-

ine Toyota fuel tank cap designed

for your vehicle. Doing so may

cause a fire or other incident

which may result in death or seri-

ous injury.

PCS (Pre-Collision Sys-

tem)

The pre-collision system
uses sensors to detect
objects (



P.156) in the path

of the vehicle. When the
system determines that the
possibility of a frontal colli-
sion with a detectable
object is high, a warning
operates to urge the driver
to take evasive action and
the potential brake pressure
is increased to help the
driver avoid the collision. If
the system determines that
the possibility of a collision
is extremely high, the
brakes are automatically
applied to help avoid the
collision or help reduce the
impact of the collision.

The pre-collision system
can be disabled/enabled
and the warning timing can
be changed. (



P.164)

156

■

Pre-collision warning

When the system determines
that the possibility of a collision
is high, a buzzer will sound and
an icon and warning message
will be displayed on the
multi-information display to urge
the driver to take evasive action.
If the detectable object is a vehi-
cle, moderate braking will be
performed with the warning.

If the system determines that
the accelerator pedal is strongly
depressed, the following icon
and message will be displayed
on the multi-information display.

WARNING

■

For safe use

●

Driving safely is solely the

responsibility of the driver. Pay

careful attention to the sur-

rounding conditions in order to

ensure safe driving.

Never use the pre-collision sys-

tem in place of normal braking

operations. This system cannot

help avoid or reduce the impact

of a collision in every situation.

Over-reliance on this system to

drive the vehicle safely may

lead to an accident resulting in

death or serious injury.

●

Although the pre-collision sys-

tem is designed to help avoid or

help reduce the impact of a col-

lision, its effectiveness may

change according to various

conditions. Therefore, it may not

always be able to achieve the

same level of performance.

Read the following items care-

fully. Do not overly rely on this

system and always drive care-

fully.

At an intersection, etc., if the
system determines that the pos-
sibility of a collision with an
approaching vehicle or motorcy-
cle is high, the pre-collision
warning and pre-collision brak-
ing will operate.
Depending on the intersection,
assistance may not operate cor-
rectly.

WARNING

■

Pre-collision braking

●

When the pre-collision braking

function is operating, a large

amount of braking force will be

applied.

●

The pre-collision braking func-

tion is not designed to hold the

vehicle stopped. If the vehicle is

stopped by pre-collision brake

control, the driver should oper-

ate the brakes immediately as

necessary.

●

The pre-collision braking func-

tion may not operate if certain

operations are performed by the

driver. If the accelerator pedal is

being depressed strongly or the

steering wheel is being turned,

the system may determine that

the driver is taking evasive

action and possibly prevent the

pre-collision braking function

from operating.

●

If the brake pedal is being

depressed, the system may

determine that the driver is tak-

ing evasive action and possibly

delay the operation timing of the

pre-collision brake control.

■

Emergency steering assist

●

The emergency steering assist

will be canceled when the sys-

tem determines that lane depar-

ture prevention control has

completed

●

Depending on operations per-

formed by the driver, emer-

gency steering assist may not

operate or operation may be

canceled.

• If the accelerator pedal is

depressed strongly, the steering

wheel is turned heavily, the

brake pedal is depressed, or the
